exposure level.

image, set the value to +2. If you want to underexpose the scene,
set value to -2.

Exposure mode
Options are
•
Auto (default)—Automatically sets the Exposure time. You
can manually set the Gain control.
•
Shutter Priority—Allows you to manually set the Exposure
time and Gain control. Choose longer exposures to create an
impression of motion. Choose shorter exposures to ensure
that the motion is effectively frozen in the resulting image.

and Iris adjustment to control the distance between the
nearest and farthest objects in a scene that appear acceptably
sharp in an image.
•

Gain control, and Iris adjustment. Selecting this option sets
the Switch Mode to Day on the Camera page.

Threshold on the Camera page.
